iconizr

takes your SVG drawings and processes them to a CSS
icon kit,coming in several different flavors. It prefers
high-resolution (retina) SVG over PNG icons,
data URIs over CSS sprites and single images and provides
fallbacks for even the least capable browsers. It outputs Sass
along with (or instead of) CSS code.
To start using iconizr, simply

drop your SVG icons here

(or click to select them).

With this free service, you may process up to 50 icons in a
single pass, with each icon file being 300 kB or less in size.
Icons will be limited to a maximum of 300 x 300 pixels resolution.
If you need more, please feel free to download and setup iconizr on your local machine (or drop me a line).*
